Hi, My environment: Ubuntu 16.4 CPU 16 cores 16 GB Memory SSD disk. 200 text fields. I have one node. We use 4 threads with bulk api and partial updates. We see that the GC Duration is ~150 ms, is it normal? Can we increase the indexing rate (current is ~2000 s)? because we don’t see any bottleneck on CPU and Disk. ![image](https://us1.discourse-cdn.com/elastic/original/3X/6/b/6b2c645969fb7956172e25248eb20100febb1f41.png) ![es2](https://us1.discourse-cdn.com/elastic/original/3X/1/8/18de8d9d5149b1cdd286f74aa2e5ddac654d5d95.png) ---
